T0 all whom t muy concern:

Be it known that We, GEORGE U. ROULET and WILLIAM F. YOUNG, of Toledo, county of Lucas, and State of Ohio, have invented certain new and useful Improvements in Mechanism for Coiling Spirals; and we do hereby declare that the following is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form part of this specification.

Our invention relates to a mechanism for coiling spirals, and has for its object to provide mechanical means whereby spirals for studs, pins, dac., may be coiled with mechanical perfection,with means for automatically releasing the coils after formation.

A further object is to provide mechanical means for coiling a spiral after the setting of the jewel, thereby facilitating the work and presenting a more perfectly finished article than heretofore.

A Jfurther object is to combine a mechanism for shaping the wire of the coil into an oval or other form in crosssection,as desired, with means for passing a portion of the wire over forms to leave the same of normally round form in crosssection,whereby the wire in each semirevolution of the rollers is shaped for the length desired for the coil,with a portion of normal shape for attachment to the setting, with attachment for coiling mechanism.

In the drawings, Figure 1 is a side elevation of the shaping and coiling mechanism. Fig. 2 is an end elevation showing the coiling mechanism in end view. Fig. 3 is an end elevation showing the crank and push-rod. Fig. 4 is an enlarged end view oi' the ooiling mechanism. Fig. 5 is a sectional view showing the coiling mechanism with a coil properly positioned within the revoluble coiler and conned by the grooved revoluble former. Fig, 6 is an elevation ofthe coiler. Fig. 7 is a plan View of one of the shaping-rollers. Fig. 8 is a longitudinal vertical section of the power-shaft, showing the driving-gear, shaping-roller, coiler, and means for advancing the coiler to release the coil when formed. Fig. 9 is a side elevation of the ceiling mechanism detached from the power mechanism, and Fig. 10 is an elevation of a finished stud; 1 designates the base, from which rises a standard 2, recessed centrally at 3 to receive site points is plain, as at 10. Grooves 9 may Y be of any desired contour and form the wire in anydesired shape in cross-section. Rollers 4 are of a diameter to form sufficient wire for a coil in each half-revolution, and the plain portion allows the wire to pass between the rollers at this point without changing its shape, thereby leaving a portion intact for the stem attached to the setting.

The coiling mechanism comprises a tubular body portion, which may be shaft 6 or, if to be used by hand, a tubular body l1, the outer end 12 of the tubular body being reduced in diameter and externally threaded, there being a wheel 13, centrally perforated and internally screw-threaded, run upon the threaded end 12. Wheel 13 is provided upon its outer side with a grooved former 14, revolubly secured upon the wheel. The central longitudinal orifice 15 in the tubular portion is preferably of two diameters. The larger diameter 1G is for the purpose of housing a coiled spring 17, which rests against the wall of the chamber at one end, with the opposite end of the spring secured to a rod 18, passing `'through the tubular portion at its rear end and provided with a knob 19, and at its forward end enlarged and formed with a tubular portion 2O and longitudinal slot 21, connecting with a transverse slot 22. By this arrangement the spring normally urges the rod and slotted tubular portion toward the rear end of shaft 6, and pressure upon the knob advances thesame against the tension of the spring.

cut away at 23 to form a shoulder or projece tion 24 to engage with the wire.

The screw-threaded end l2 is In operation shaft 6 is revolved, thereby revolving rollers 4f, when the wire is inserted and shaped. Any desired length of wire is passed through the rollers, and the wire is then cut at the plain portion, each section forming a sufficient length to form a coil. The setting may be secured to the round portion 25 of the wire, and the portion necessary to form a coil is bent at right angles thereto, when the Wire is inserted in the tubular portion 20, the angled portion passing down the slot 21 and seating in slot 22 and engaged with projection 24 of the end 12. Wheel 13 is run upon the thread of the end l2 until the groove of the former-Wheel 14 coincides with the projecting end of the wire, when upon revolving wheel 13 the former-wheel 14 travels concentrically of the end 12 and coils the wire into the desired number of oonvolutions. After the wire is coiled wheel 13 is turned to cause the former-wheel 14 to pass oi of the end of the wire, and knob 19 is pushed inwardly to cause the slotted end to advance and release the coil from projection 24, when the coil may be removed either by turning the coil to release it from slot 22 or by turning knob 19 and rod 18, and consequently the slotted end, to Withdraw the slotted portion from the wire.

For some forms of coils the coiling mechanism may be operated by hand, in which event the tubular portion 1l may be grasped in the hand and held while wheel 13 is being revolved.

What we claim is- 1. In a machine for coiling spirals, rollers provided with a series of peripheral grooves, and grooves in the rollers arranged at dia metrically opposite points, said grooves extendinglongitudinally of the rollers and form- 4o ing ablank space between the ends of the peripheral grooves, whereby a wire passed between the rollers is formed into the desired shape in cross section by the peripheral grooves, and is left intact for a distance comprising the width of the longitudinal grooves.

2. In a mechanism for coiling spirals, a tubular body portion, having a threaded end, a rod longitudinally movable in the body portion, a spring upon the rod to normally retract the same, a tubular portion upon the end of the rod, having a longitudinal and a transverse slot, a projection upon the end of the threaded portion, and an internallythreaded wheel upon the threaded portion, having a grooved former-Wheel ,journaled thereon.

3. In a mechanism for coiling spirals, abody portion formed with a central longitudinal perforation, a rod located in the perforation, a spring upon the rod for normally retracting the same, a knob upon one end of the rod, and coiling mechanism upon the opposite end, having an opening to receive the stem of the spiral, and a transverse groove to receive the wire of the coil, a projection upon the body portion to engage with the wire of the coil, and a revoluble coiler-wheel arranged to 1n ove concentric to thebody portion.

In testimony that we claim the foregoing as our own we hereby affix our signatures in pres-y ence of two Witnesses.
